1

Set Up Page Size and Margins

The first and most critical step is setting your Word document to the correct page size and margins for your chosen KDP trim size.

In Microsoft Word:

1. Go to Layout → Size → More Paper Sizes
2. Set Width and Height to your trim size (e.g., 6" width, 9" height)
3. Go to Layout → Margins → Custom Margins
4. Set the following margins:

SettingValue (6×9 example)Notes
Top0.5" (12.7mm)Minimum 0.25", we recommend 0.5"
Bottom0.625" (15.9mm)Minimum 0.25", we recommend 0.625"
Inside (Gutter)See calculatorDepends on page count — use our [Margin Calculator](/guides/kdp-margin-calculator/)
Outside0.5" (12.7mm)Minimum 0.25", we recommend 0.5"
Gutter0"Set to 0 — use Inside margin instead
Multiple pagesMirror marginsEssential for left/right page layout
Tip: Select "Mirror margins" under the Multiple pages dropdown. This ensures left and right pages have mirrored margins, which is essential for a bound book.
Important: In Word, set the Gutter field to 0 and use the Inside margin field for your gutter value. Using both will double your inside margin.

Choose and Configure Fonts

Font choice significantly affects readability and the professional feel of your book. Here are our recommendations:

GenreBody FontSizeHeading Font
Fiction / NovelsGaramond, Palatino, Georgia11–12ptSame as body or complementary serif
Non-FictionCalibri, Helvetica, Minion Pro10.5–11ptBold variant or contrasting sans-serif
MemoirGaramond, Baskerville11–12ptSame family, larger size
PoetryGaramond, Palatino11ptItalic or small caps variant
Children'sCentury Schoolbook, Sassoon14–16ptFun, readable display font

To set your default font in Word:

1. Select all text (Ctrl+A)
2. Go to Home → Font
3. Choose your font and size
4. Click Set As Default → All documents based on this template

Tip: Use only fonts you have the licence to embed in a PDF. All Windows system fonts (Garamond, Georgia, Palatino Linotype) are safe to use. Google Fonts are also free for commercial use.

Set Up Paragraph Styles

Using Word's built-in styles ensures consistency and makes generating a Table of Contents possible. Modify these styles:

Body Text / Normal style:

• Line spacing: 1.3 (fiction) or 1.15 (non-fiction)
• First line indent: 0.3" (fiction) or 0" with space after (non-fiction)
• Space before: 0pt
• Space after: 0pt (fiction) or 6pt (non-fiction)
• Alignment: Justified

Heading 1 (Chapter titles):

• Font size: 18–24pt
• Space before: 72pt (starts chapter 1/3 down the page)
• Space after: 24pt
• Page break before: Yes
• Keep with next: Yes

Heading 2 (Subheadings):

• Font size: 14–16pt
• Space before: 18pt
• Space after: 6pt
• Keep with next: Yes

Tip: Right-click any style in the Styles pane and select "Modify" to change its properties. This updates all text using that style throughout your document.

Configure Headers and Footers

Professional books use headers (running heads) to show the book title and chapter name, and footers for page numbers.

Setting up different odd/even headers:

1. Double-click in the header area to open Header & Footer Tools
2. Check "Different Odd & Even Pages"
3. Check "Different First Page"
4. On even (left) pages: Add book title, left-aligned
5. On odd (right) pages: Add chapter title, right-aligned
6. Leave the first page of each chapter header blank

Page numbers:

• Position: Bottom centre or bottom outside corner
• Start numbering from 1 on the first page of Chapter 1
• Front matter (title page, copyright, TOC) uses Roman numerals (i, ii, iii) or no numbers
• Use section breaks to control numbering independently

Important: Each section break creates a new section with independent headers/footers. Uncheck "Link to Previous" in each new section to prevent changes from cascading.
5

Create Front and Back Matter

Professional books include standard front and back matter pages. Here is the recommended order:

Front matter (before Chapter 1):

1. Half-title page — Book title only, centred
2. Title page — Full title, subtitle, author name
3. Copyright page — Copyright notice, ISBN, publisher, "Printed in Great Britain"
4. Dedication (optional)
5. Table of Contents
6. Foreword/Preface (optional)

Back matter (after final chapter):

1. Acknowledgements (optional)
2. About the Author
3. Also By — List your other books
4. Index (non-fiction only)

UK copyright page template:
Copyright © 2026 [Your Name]
All rights reserved.
ISBN: [Your ISBN]
Published by [Publisher Name]
Printed and bound in Great Britain
First published 2026
6

Insert Section and Page Breaks

Section breaks are essential for controlling headers, footers, and page numbering independently in different parts of your book.

Where to use section breaks:

• Between front matter and Chapter 1 (to change page numbering)
• Between each chapter (if you need different headers per chapter)
• Before back matter (to change or remove headers)

How to insert:

1. Place cursor at the end of the section
2. Go to Layout → Breaks → Section Breaks → Next Page
3. For chapters starting on right-hand pages: use Odd Page section break

Page breaks vs Section breaks:

Break TypeUse ForShortcut
Page BreakStarting a new page within a sectionCtrl+Enter
Section Break (Next Page)New section on next pageLayout → Breaks
Section Break (Odd Page)New section on next right-hand pageLayout → Breaks
Important: Never use multiple Enter keys to push text to a new page. Always use proper page or section breaks. Extra Enter keys will shift when the document is reformatted.
7

Generate Table of Contents

If you have used Heading styles consistently, Word can automatically generate a page-numbered Table of Contents.

To generate a TOC:

1. Place your cursor where you want the TOC
2. Go to References → Table of Contents
3. Choose a built-in style or select Custom Table of Contents
4. Set "Show levels" to 1 (chapters only) or 2 (chapters + subheadings)
5. Ensure "Use hyperlinks" is unchecked for print
6. Click OK

To update the TOC after changes:

Right-click the TOC and select "Update Field" → "Update entire table"

Tip: Always update your TOC as the very last step before exporting to PDF. Page numbers will change as you make edits, so the TOC should be refreshed at the end.
8

Export as KDP-Ready PDF

The final step is exporting your Word document as a PDF that meets Amazon KDP's requirements.

In Microsoft Word:

1. Go to File → Save As (or Export)
2. Choose PDF as the file type
3. Click Options and ensure:
  • "ISO 19005-1 compliant (PDF/A)" is checked
  • "Bitmap text when fonts may not be embedded" is unchecked
4. Set quality to "Standard (publishing online and printing)"
5. Save

Verify your PDF:

• Open the PDF and check all pages look correct
• Verify fonts are embedded (File → Properties → Fonts in Adobe Reader)
• Check page size matches your trim size exactly
• Ensure page count is even (add a blank page at the end if odd)

Important: Word's built-in PDF export does not create true PDF/X-1a:2001 files. For best results, use Adobe Acrobat Pro to convert, or use [our formatting service](/order/) which produces fully compliant PDFs.
Alternative: If you have Adobe Acrobat, use File → Print → Adobe PDF with the "PDF/X-1a:2001" preset for a fully KDP-compliant PDF.

When to format Word for KDP yourself

Microsoft Word is genuinely capable of producing a KDP-acceptable paperback PDF, provided the page setup, styles, and export options are all configured correctly. Authors who succeed with Word usually share three traits:

  • The book is mostly text with simple chapter structure.
  • The author is comfortable using Word styles rather than direct formatting.
  • The book is short enough (under 300 pages) that small drift errors do not compound.

If any of those is missing, the time you spend fighting Word usually exceeds the cost of a professional formatter.

When a professional formatter saves time

Word starts to break down on books that have any of the following:

  • More than 350 pages of body text.
  • More than ten in-line images or any image that needs to span a full page.
  • Tables that need to fit precisely within trim margins.
  • A glossary, index, or end-notes that must stay synchronised across re-flows.
  • A target trim size that Word does not handle smoothly (e.g. 5.06" × 7.81").

For books like these, our formatting service is usually faster and produces a cleaner final file.

Common Word-to-KDP mistakes

  • Setting the Gutter field instead of the Inside margin (doubles the gutter).
  • Using multiple Enter presses instead of page breaks (shifts when re-flowed).
  • Forgetting to embed fonts on PDF export (rejection guaranteed).
  • Leaving track-changes accept/reject markers in the file.
  • Using soft hyphens or non-breaking spaces from earlier Word versions.
  • Generating the TOC before the manuscript is final (numbers shift).
  • Exporting with hyperlinks left enabled for a print-only paperback.
  • Using copyrighted screenshot images without a written licence.

Run through this list before exporting your PDF — these mistakes account for the majority of Word-to-KDP rejections in our audits.

How to verify your PDF is KDP-ready

Once Word has produced your PDF, do three checks before uploading:

  1. Open in Adobe Reader and confirm File → Properties → Fonts lists every font as "Embedded Subset".
  2. Check page count is even and within KDP's range for your trim size.
  3. Run a free Readiness Score — it catches font-embed, page-count and margin issues in under 30 seconds.

A file that passes all three is almost always cleared by KDP automated review on the first attempt.

Frequently asked questions

Do I set the Gutter field or the Inside margin field in Word?

Set the Gutter field to 0 and put your gutter value in the Inside margin field. Using both will double the inside margin and push your text away from the spine.

Why does Word's built-in PDF export not produce a fully KDP-compliant file?

Word's PDF export does not generate a true PDF/X-1a:2001 file. For a fully compliant PDF, use Adobe Acrobat with the "PDF/X-1a:2001" preset, or run the file through a dedicated conversion tool.

What body font size should I use for a fiction paperback?

For fiction, use a serif font like Garamond, Palatino, or Georgia at 11–12pt with line spacing of around 1.3. Non-fiction typically uses 10.5–11pt sans-serif body text.

How do I make chapters start on right-hand pages in Word?

Use an Odd Page section break (Layout → Breaks → Section Breaks → Odd Page) before each chapter. Word will automatically insert a blank page where needed so every chapter opens on a right-hand (recto) page.
